SPECIFICATION forming part of Letters Patent No. 465,239, dated December 15, 1891.

Application filed May 18, 1891. Serial No. 393,107. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM BURLING, a citizen of the United States, and a resident of Oxford, Chester county,l Pennsylvania, have invented certain Improvements in Steam- Generators or Water-Heaters, of which the following is a specification.

My invention consists of certain improvements in that class of steam-generators or water-heaters which are used for house-heating purposes and aresometimestermedhouse boi1ers,one object of my invention being to provide for the ready repairing of different parts of the boiler independently of the other parts, or to render inoperative anydesired section of the boiler without aifecting the other sections, a further object being to increase the water capacity of the boiler and to volume indifferent parts of the boiler, and a still further object being` to provide for the effective action of the products of combustion upon the heating-surfaces of the boiler. These objects I attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in Which- Figure l is a vertical section' of a steamgenerator or water-heater constructed in accordance with my invention, the section being taken on the line 1 2, Fig. 3. Fig. 2 is a vertical sectional view on the line 3 4, Fig. 3. Fig. 3 is a sectional plan view on the line 5 6, Fig. l. Fig. 4 is a sectional plan View on the line 7 8, Fig. 2; and Figs. 5, 6, and 7 are detached perspective views of the various sections composing the boiler.

The boiler consists of three main parts, which may be denominated, respectively, the body,thedome,and the magazine The body consists of a number of sections A, there being in the present instance four of these sec; tions, each consisting of a quadrant and having an outer wall a, inner Wall b, and end walls d, and top and bottom f and g. These sections when fitted together inclose the combustion-chamber F and fire-pot G, the inner wall being by preference slightly deflected at the lower portion,.so as to provide for the increased diameter of the lire-pot, as shown in Figs. l and 2. The inner wall of each secan increased heating-surface, and the upper portion of each of the inner Walls of said bodysections is tapered inwardly so as to increase the capacity of each section in the upper portion thereof. This increase of capacity is provided for, because in each of t-he'end walls of each section of the body of the boiler there is a recess h, these recesses, when the various sections of the body are fitted together, forming discharge-fines for the passage of the products of combustion, as described hereinafter. These flue-chambers therefore detract from the water capacity of those portions of the body-sections in which they are formed.

able threaded openings formed in the bottom platespof the dome-section and in the top plates of the body-sections, as shown in Fig. 1.

The magazine is composed of a series of sections D, of whichg there are four in the present instance, each section comprising inner and outer walls, end walls, top and bottom, and the top plate of each section having a projecting nozzle m, which enters an opening in the bottoni plate of the dome-section, suitable packing being interposed to make a iireproof and water-tight joint.

Each magazine-section is suspended from the dome-section by means of a bolt n, the lower end of which engages with a transverse rod n in the magazine-section, the upper end passing through an opening in the top plate of the dome-section and being threaded for the reception of a nut bearing upon said top tion of the body is corrugated, so as to form corrugated inner walls of the body-sections of the boiler andwith the outer walls of the magazine-sections, the products of combustion then impinging upon the top plates of the body-sections and the bottom plates of the dome-sections, and then, owing to the check-ring p, descending the flue-spaces h, and finally escaping laterally therefrom and clrculating in the chamber between the outer walls of the body-sections and the outer casing before escaping from the latter through a suitable pipe leading to the chimney, any

desired arrangement of baffle-plates being located in this chamber for the purpose of causing the products of combustion to take a circuitous course through the same. l

The sections of the body, dome, check-ring, magazine, and outercasing are provided With perforated lugs for the reception of suitable bolts for securing said sections together.

The feed-Water or return pipes s com muni-4 cate with the lower portion of the body-sections of the boiler and the steam or hot water discharge-pipes t lea-d from the sections of the dome, as shown in Fig. l.

Having thus described my invention, I claim vand desire to secure by'Letters Patentl. The body of the boiler, composed of a number of sections, each complete in itself, and having fiile-spaces in the ends extending to the outside of the section some distance above the bottom of the same, each sectionl composed of a number of sections, each complete in itself, with flue-spaces extending from the top of each section to the outer side of the same some distance above the bottom, 'substantially as specified.

3. The combination of the dome of the boiler with the magazine independent of the body and composed of a number of segmental water-chambered sections communicating at their upper ends with the interior of the dome, substantially as specified.

4. The combination of the body of the boiler, the dome, and the magazine, each composed of Sections complete in itself, and said body-sections having iue-spaces, with connections between said body-sections and magazine-sections and the dome-sections, substantially as specified.

5. The combination of the dome, the magazine-sections having transverse bars, suspension-bolts engaging with said bars and passing tl1rough-the dome, and nozzles through which the magazine-sections communicate with the dome, substantially as specified.

6. The combination of the body-sections VILLIAM BURLING.A
